sli w/ a 600w PSU

Depends on what 600W power supply it is. A single 98000GTX+ recommended is 450W with 24 amps. with one card. Why not get a GTS 250 instead of a 9800GTX+?

a 600 watt would be enough, the specs say 450 for one and 550 for sli.

Wattage doesnt mean anything, wattage ratings are the reasons there are idiots who buy "900W" and "800W" power supplies that provide less power than a 400W corsair.
 
depends on the brand, assuming its a decent psu(corsair, pcpw&c, silverstone)as of right now, i'm running my pair of gtx 285's on my silencer 610(i can't say i would recommend it, but it works :P)
 
there was a guy on here that used to run 2 8800GTS 512's on a Corsair 520W psu.

my recommendation, get a corsair PSU.

and then have fun.

I have a 750W corsair on my system (look at sig), and i have barely even strained it.

im probably using about 500 - 550W while gaming...

but the comments here are completely correct.

ITS ABOUT THE AMPS!!!!

it does play its role as with all electronics

but in terms of if it can power something, amps are more important

I would rather have a 600W PSU with 55A, than a 1000W PSU with 40A

thats basically it.
 
to Xfire, you need an intel motherboard (P35, P45, X38, X48, X58)

to SLI, you need an nvidia motherboard

But, if you have the new X58 motherboard, i think it supports both...

The 600W 40 amp. If a power supply claims 800W but only 40 amps. on the 12V rail, alot of the watts are on the 3.3/5V rails. So it wont have no where near 800W on the 12V rail. A good power supply that claims 600W on the 12V rail should have around 50 amps. on the 12V.
 
Alright i know this is unrealistic, but what if it was the same everything, the only differences in the psu's were the diff. amounts of watts. Which one then?

Just curious bomberboysk,

So wattage means absolutly nothing?:eek:

Generally speaking, its not something you should be looking at only, what is more important is the +12v rail ratings as well as manufacturer.

No idea what you are trying to say, wattage ratings come from the amperage available over all the rails(supposedly). Eg- cheap power supplies will have anywhere from 30-50A on the 3v and 5v rails and alot less on the 12v rail.
 
what he is trying to say is that the specs are identical, but one delivers 800w, and the other 600w

but, that is not the real life case. its misleading.

in real life, look for amps, mostly on the 12v line. the wattage is your *reference* for a PSU

usually the more wattage, the more amps on the 12v line (usually the case with good PSU manufacturers like corsair)

i went for a 750w (even though its overkill) for that reason. i would prefer my PSU to run under relaxed conditions, that to be under slightly more strain. remember, the PSU is the most important part of you computer... a Bad PSU can create ALOT of problems...

my corsair has 60A on the 12v line.

more than enough.

You got to look at it like this.

Say you have one power Supply rated at
500W total with 35 amps on the 12V.

Another one rated 600W with 35 amps on the 12V.


The difference between the two is the 600W model has more of its watts on the 3.3/5V rail then the 500W. So the total wattage on the 12V rail is about the same between the two.
